For the technical scheme of dealing with problems
The first mode of the present invention is a kind of cooling device, it is characterized in that, comprise hot link in the piece and have a plurality of hot links in the radiating fin group of the fin of the described piece that is heated of being heated of heater element, set flowing of cooling air and be the direction parallel with the described piece that is heated, the file that flows to along described cooling air disposes a plurality of described radiating fin groups, among described a plurality of radiating fin group, radiating fin group's the spacing of fin that is disposed at described cooling air weather side is larger than the radiating fin group's who is disposed at described cooling air downwind side spacing of fin.The second mode of the present invention is a kind of cooling device, it is characterized in that, comprise hot link in the piece and have the radiating fin group that a plurality of settings are arranged at the fin on the described piece surface that is heated of being heated of heater element, set flowing of cooling air and be the direction parallel with the described piece that is heated, the file that flows to along described cooling air disposes a plurality of described radiating fin groups, among described a plurality of radiating fin group, radiating fin group's the spacing of fin that is disposed at described cooling air weather side is larger than the radiating fin group's who is disposed at described cooling air downwind side spacing of fin.
Third Way of the present invention is a kind of cooling device, it is characterized in that, comprise hot link in the piece that is heated of heater element, setting is arranged at a plurality of heat pipes on the described piece surface that is heated, with have a plurality of radiating fin groups that are installed on the fin of described heat pipe in the direction parallel with the described piece that is heated, set flowing of cooling air and be the direction parallel with the described piece that is heated, the file that flows to along described cooling air disposes a plurality of described radiating fin groups, among described a plurality of radiating fin group, radiating fin group's the spacing of fin that is disposed at described cooling air weather side is larger than the radiating fin group's who is disposed at described cooling air downwind side spacing of fin.
In described each mode, arrange a plurality of radiating fin groups for cooling airflow to parallel or almost parallel ground, and consist of the surface of each fin of described radiating fin group for cooling airflow to parallel or the installation of almost parallel ground.So, become the structure that cooling air flows swimmingly between fin.Become following structure: although it is identical or roughly the same to consist of same radiating fin group's the spacing of fin of each fin,, for each radiating fin group, spacing of fin is different, that is to say, the radiating fin group is different, and is also different in abutting connection with the spacing of fin between fin.And radiating fin group's the spacing of fin that is disposed at the cooling air weather side is larger than the radiating fin group's who is disposed at the cooling air downwind side spacing of fin.
So, the spacing of fin of radiating fin group by making weather side is larger than the radiating fin group's of downwind side spacing of fin, in the situation that use same fan, can prevent from reducing by air quantity and the wind speed of the cooling air among the weather side radiating fin group, and can suppress the cooling air temperature and rise.And, rise because can be suppressed at the cooling air temperature of weather side, so the lower cooling air of side radiating fin group supplying temperature alee.In the specification, " radiating fin group " refers to a group fin that obtains to arranging in vertical direction a plurality of fins with respect to cooling airflow.

And, will be configured to mutually at grade at the first fin 4a of highest distance position setting with for the second fin 5a of piece 2 in the highest distance position setting that be heated for the piece 2 that is heated.Similarly, will be configured to mutually at grade at the first fin 4a of proximal most position setting with for the second fin 5a of piece 2 in the proximal most position setting that be heated for the piece 2 that is heated.The first radiating fin group's 4 the inscape i.e. geomery of each first fin 4a is mutually identical, makes the first radiating fin group's 4 side surface part become the state of the edge part alignment of the first fin 4a.The second radiating fin group's 5 the inscape i.e. geomery of each second fin 5a is mutually identical, makes the second radiating fin group's 5 side surface part become the state of the edge part alignment of the second fin 5a.
In the cooling device 1 of the first embodiment, supply with cooling air in the from left to right direction of Fig. 1.And then, cooling device 1 is set, parallel or almost parallel ground flows so that cooling air is for piece 2 surface that is heated, and that is to say, for the surperficial parallel or almost parallel ground of each the first fin 4a and each second fin 5a flowing.So, because cooling air at first passes through in the first radiating fin group 4 along each first fin 4a, then, the cooling air that has passed through the first fin fin 4 enters among the second radiating fin group 5,5a passes through in the second radiating fin group 5 along each second fin, becomes the obstacle of cooling air so can prevent the first radiating fin group 4 and the second radiating fin group 5.And, forming space 8 between the radiating fin group between the first radiating fin group 4 and the second radiating fin group 5.Because space 8 between this radiating fin group, fin is not the fin 44a of the such plate of conventional example, but becomes the state that is split into the first fin 4a and the second fin 5a, forms the first radiating fin group 4 and the second radiating fin group 5.
In the cooling device 1 of the first embodiment, the size of the first fin 4a is, width 480mm, length 300mm, thickness 0.5mm, and the space 4b of the first fin 4a is 6.5mm.On the other hand, the width of the second fin 5a is also identical with the first fin 4a with the identical 480mm of being of the first fin 4a, thickness to be 0.5mm, but because reason described later, the length of the second fin 5a is the 495mm longer than the first fin 4a.The space 5b of the second fin is 3mm.And the size of the piece 2 that is heated is that width 500mm, length 1000mm, thickness 25mm, end view are that the size of the heat pipe 3 of U word shape is, caliber 15.88mm, height 200mm, width 115.88mm.End view is that the section shape of pipe of the heat pipe 3 of U word shape is circular.The viewpoint that never cooling capacity is exerted an influence, the width in space 8 is preferably narrow as far as possible between the radiating fin group, also can make the first fin 4a end face with facing to the second fin 5a end face of this first fin 4a near.In the cooling device 1 of the first embodiment, the width in space 8 is 5mm between the radiating fin group.
Described the first fin 4a and the piece 2 that is heated all are the good flat sheet of metal material of heat conductivity, by manufacturings such as aluminium, aluminium alloy, copper, copper alloys.Heat pipe 3 also is by the metal material manufacturing same with the first fin 4a and the piece 2 of being heated, and for working solution, encloses with decompression state and to meet the adaptive working solution of container material.For example, in the situation that container is copper, working solution uses pure water.
The fixing means of the first fin 4a and the second fin 5a is not particularly limited, in cooling device 1, at the first fin 4a and the second fin 5a precalculated position separately hole section (not shown) is set, make it inlay insertion by inserting heat pipe 3 in this hole section, be situated between and fix the first fin 4a and the second fin 5a by heat pipe 3 at cooling device 1.
Then, use Fig. 2, Fig. 3, for the cooling device 1 of the first embodiment, the configuration relation of the first fin 4a and the second fin 5a is described.
For the configuration relation of the first fin 4a and the second fin 5a, so long as the space 4b between the first fin 4a gets final product greater than the scheme of the space 5b between the second fin 5a, be not particularly limited.Reason is, if the words of described scheme, because can reduce the pressure loss that the first radiating fin group 4 causes, so can suppress the air quantity of the cooling air by the second radiating fin group 5 and the reduction of wind speed, and, by reducing the first fin 4a number of the first radiating fin group 4, the temperature that can suppress to pass through the first radiating fin group's 4 cooling air rises.
As shown in Figure 2, in the cooling device 1 of the first embodiment, the spacing of fin that is configured to the first radiating fin group 4 and the second radiating fin group 5 is the relation of integral multiple (among Fig. 2, the first radiating fin group 4 and the second radiating fin group's 5 spacing of fin is 2:1).And then, make the first radiating fin group 4 consistent with the second radiating fin group's 5 spacing of fin phase place.That is to say, configure the second fin 5a of the second radiating fin group 5 at the same plane of each the first fin 4a, and then also configure again 1 the second fin 5a at the position that is equivalent to 4b width centre in space between the first fin 4a.By becoming so the fin configuration, can prevent that the second fin 5a from becoming the obstacle that has from left to right passed through the cooling air 7 among the first radiating fin group 4 at accompanying drawing, can suppress the air quantity of cooling air 7 and pressure that wind speed is subject to the second fin 5a and loss.So, become following structure: the cooling air 7 that has passed through among the first radiating fin group 4 flows in being arranged at the second radiating fin group 5 of downwind side swimmingly.
And, for example, as shown in Figure 3, even the relation that the first radiating fin group 4 and the second radiating fin group's 5 spacing of fin is become be not integral multiple is (among Fig. 3, the first radiating fin group 4 and the second radiating fin group's 5 spacing of fin is 3:2), also can suppress the air quantity of the cooling air 7 by the second radiating fin group 5 and the reduction of wind speed.In this scheme, the first radiating fin group 4 and the second radiating fin group's 5 spacing of fin phase place is inconsistent.That is to say, the structure of the same plane of the first fin 4a configuration the second fin 5a with not at the structure alternative arrangement of same plane configuration the second fin 5a of the first fin 4a.So, in the situation of the fin of Fig. 3 configuration, produce following position in the second radiating fin group: the position that cooling air 7 flows swimmingly and the second fin become obstacle and position that cooling air 7 is difficult to flow.
In the configuration relation of described the first fin 4a and the second fin 5a, thereby be subject to the viewpoint of the caused pressure air quantity of the second fin 5a and wind speed loss in the second radiating fin group 5 from preventing from having passed through cooling air 7 the first radiating fin group 4, the preferably configuration of Fig. 2, namely the first radiating fin group 4 and the second radiating fin group's 5 spacing of fin is the relation of integral multiple, and the phase place of spacing of fin is consistent.
Then, use Fig. 4 that the deblocking temperature that is heated of the cooling device 41 of be heated deblocking temperature and the conventional example of the cooling device 1 of the first embodiment is described.Should illustrate, the deblocking temperature that is heated is tried to achieve by numeric value analysis.The structure of the cooling device 1 of the first embodiment that uses in numeric value analysis is identical with described structure.On the other hand, in the structure of the cooling device 41 of conventional example, the length of fin 44a is the width sum in space 8 between the length of length, the second fin 5a of the first fin 4a and radiating fin group, radiating fin group 44 spacing of fin is identical with the second radiating fin group's 5 spacing of fin, in addition, identical with cooling device 1 structure of in numeric value analysis, using.Carry out numeric value analysis with following condition, will from the heat of the total 11000W of each heater element 50-1,50-2,50-3,450-1, the impartial heating of 450-2,450-3 respectively heat be input to the piece 2,42 that is heated, and the cooling air that blows to the first radiating fin group 4 and radiating fin group's 44 front is 20 ℃, wind speed 5.8m/s.
As shown in Figure 4, although the temperature of the piece windward section of being heated of cooling device 1 slightly has rising than the cooling device 41 of conventional example, temperature and the conventional example of the piece central portion that is heated are equal extent, and the temperature of the piece leeward of being heated section is lower than conventional example.Therefore, the cooling device 1 of the first embodiment can reduce total weight and can improve the cooling capacity of downwind side and realize the cooling capacity homogenizing.
Then, use Fig. 5 that the localization method in space 8 between the radiating fin group of the cooling device 1 of the first embodiment is described.Should illustrate, the line chart of Fig. 5 is that among Fig. 5, " fin front end " refers to the fin end facing to a side of cooling air weather side from the Temperature Distribution on the radiating fin group 44 suitable fin 44a surfaces of selecting of the cooling device 41 of conventional example.The position in space 8 between the radiating fin group, the ratio that is to say the length of the length of the first fin 4a and the second fin 5a is not particularly limited, can suitably select, but, viewpoint from the cooling capacity that improves downwind side, preferably, as described below, determine based on the fin surface Temperature Distribution.
As shown in Figure 5, as the surface temperature of the fin 44a of a plate of conventional example along with cooling air from weather side side shifting and continue to rise alee.And space 8 is arranged at the position of the medium temperature of expression fin 44a surface minimum temperature and maximum temperature between the radiating fin group.That is to say, space 8 between the radiating fin group of location so that cut apart fin 44a in the position of the temperature difference Δ T/2 that the temperature difference Δ T five equilibrium on fin 44a surface can be cut apart, forms the first radiating fin group 4 and the second radiating fin group 5.So, when in the position of expression medium temperature space 8 being set between the radiating fin group, can form 2 radiating fin groups in the zone that each fin surface temperature approaches.So, by so that the first radiating fin group's 4 the spacing of fin with abundant cooling capacity greater than radiating fin group 44, can suppress by the air quantity of the cooling air among the second radiating fin group 5 and the reduction of wind speed.And by reducing the number of the first fin 4a, the temperature that can reduce the first radiating fin group's 4 cooling air rises, thereby can be to the lower cooling air of the second radiating fin group 5 supplying temperatures.And then, because reduce the number of the first fin 4a, can suppress the weight of cooling device 1.
And shown in the line chart of Fig. 5, the Temperature Distribution on fin 44a surface is more more sharply to reduce near weather side, and Temperature Distribution is not rectilinear form with relation from the distance of fin front end.So, in the time the temperature difference Δ T/2 position that the temperature difference Δ T five equilibrium on fin 44a surface is cut apart can being arranged between the radiating fin group space 8, the length of the first fin 4a of Length Ratio the first radiating fin group 4 of the second fin 5a of the second radiating fin group 5 is long.
Then, to the cooling device of third embodiment of the invention, use accompanying drawing to describe.Cooling device 1 at the first embodiment is provided with 2 radiating fin groups, and as shown in Figure 6, the cooling device 21 of the third embodiment of the present invention arranges 3 radiating fin groups and replaces.A plurality of end views that the cooling device 21 of the 3rd embodiment comprises the flat piece 22 that is heated, install in vertical on the surface of the piece 22 that is heated are the heat pipe 23 of U word shape, the first radiating fin group 24 who is installed on heat pipe 23, the second radiating fin group 25 and the 3rd radiating fin group 26.That the first radiating fin group 24 comprises is a plurality of (among Fig. 6 9) the first fin 24a.That the second radiating fin group 25 comprises is a plurality of (among Fig. 6 17) the second fin 25a.That the 3rd radiating fin group 26 comprises is a plurality of (among Fig. 6 33) the 3rd fin 26a.That is to say, the number of the second fin 25a of cooling device 21 is identical with the number of the first fin 4a of cooling device 1, and the number of the 3rd fin 26a of cooling device 21 is identical with the number of the second fin 5a of cooling device 1.The first fin 24a, the second fin 25a, the 3rd fin 26a all are rectangular thin plates.And, forming space 28-1 between the radiating fin group between the first radiating fin group 24 and the second radiating fin group 25, forming space 28-2 between the radiating fin group between the second radiating fin group 25 and the 3rd radiating fin group 26.
And cooled body is heater element begins to be thermally connected to the order of 250-1,250-2,250-3 successively the side that heat pipe 23 is not set from weather side piece 22 back sides that are heated.
Configuration relation for the first fin 24a, the second fin 25a and the 3rd fin 26a, so long as the space 24b between the first fin 24a is greater than the space 25b between the second fin 25a, space 25b between the second fin 25a gets final product greater than the scheme of the space 26b between the 3rd fin 26a, is not particularly limited.Reason is, if the words of such scheme, because can reduce the pressure loss that the first radiating fin group 24 causes, so can suppress the air quantity by the second radiating fin group's 25 cooling air, the reduction of wind speed, and the number of the first fin 24a reduces and the temperature that can suppress to pass through the first radiating fin group's 24 cooling air rises, and, and then because can reduce the second radiating fin group 4 caused pressure losses, so can suppress the air quantity by the 3rd radiating fin group's 26 cooling air, the reduction of wind speed, and the number of the second fin 25a reduces and the temperature that can suppress to pass through the second radiating fin group's 25 cooling air rises.As shown in Figure 6, in the cooling device 21 of the 3rd embodiment, the spacing of fin that is configured to the first radiating fin group 24 and the second radiating fin group 25 is the relation of integral multiple, and, the second radiating fin group 25 and the 3rd radiating fin group's 26 spacing of fin is the relation (among Fig. 6, the first radiating fin group 24, the second radiating fin group 25, the 3rd radiating fin group's 26 spacing of fin is 4:2:1) of integral multiple.And, make the first radiating fin group 24, the second radiating fin group 25 and the 3rd radiating fin group's 26 the phase place of spacing of fin consistent.That is to say, same plane at each the first fin 24a configures the second fin 25a of the second radiating fin group 25 and the 3rd radiating fin group's 26 the 3rd fin 26a, and then, configure the second fin 25a at the binary position of width with the space 24b between the first fin 24a, configure the 3rd fin 26a at the position with the width quartering of the space 24b between the first fin 24a.
So, by becoming the fin configuration same with cooling device 1, can prevent that the second fin 25a, the 3rd fin 26a from becoming the obstacle that cooling air flows, suppress the air quantity of cooling air and pressure that wind speed is subject to the second fin 25a, the 3rd fin 26a and loss.So, become following structure, passed through cooling air among the first radiating fin group 24 in the second radiating fin group 25 who is disposed at the first radiating fin group 24 downwind sides and be disposed to flow swimmingly among the 3rd radiating fin group 26 of the second radiating fin group 25 downwind sides and further improve the cooling capacity of downwind side.
Then, to the cooling device of the second embodiment of the present invention, use accompanying drawing to describe.The cooling device 1 of the first embodiment is to form 2 radiating fin groups by fin, described fin is installed to for the piece that is heated with the piece that is heated with becoming parallel shape and erects the heat pipe that arranges in vertical, substitute it, such as Fig. 7, shown in Figure 8, the cooling device 31 of the second embodiment of the present invention is the radiator that is formed 3 radiating fin groups by a plurality of fins, and described fin is erect in vertical for the piece that is heated and arranged.The first radiating fin group 34, the second radiating fin group 35 and the 3rd radiating fin group 36 that the cooling device 31 of the second embodiment comprises the flat piece 32 that is heated, installs on piece 32 surfaces that are heated.
Shown in Fig. 8 (a), the first radiating fin group 34 becomes at flat bottom surface sections 34c and erects the structure that a plurality of (among Fig. 8 (a) 6) the first fin 34a is set.Be arranged so that any first fin 34a is vertical for bottom surface sections 34c, and the first fin 34a surface is parallel for the flow direction of cooling air, its spacing of fin is for uniformly-spaced.Shown in Fig. 8 (b), the second radiating fin group 35 becomes at flat bottom surface sections 35c and erects the structure that a plurality of (among Fig. 8 (b) 11) the second fin 35a is set.Be arranged so that any second fin 35a is vertical for bottom surface sections 35c, and the second fin 35a surface is parallel for the flow direction of cooling air, its spacing of fin is for uniformly-spaced.Shown in Fig. 8 (c), the 3rd radiating fin group 36 becomes at flat bottom surface sections 36c and erects the structure that a plurality of (among Fig. 8 (c) 21) the 3rd fin 36a is set.Be arranged so that any the 3rd fin 36a is vertical for bottom surface sections 36c, and the 3rd fin 36a surface is parallel for the flow direction of cooling air, its spacing of fin is for uniformly-spaced.By with bottom surface sections 34c, 35c, 36c and piece 32 hot links of being heated, make the first radiating fin group 34, the second radiating fin group 35, the 3rd radiating fin group 36 and be heated piece 32 hot links.
In the cooling device 31 of the second embodiment, to be heater element begin successively to be thermally connected to piece 32 back sides that are heated that fin is not set with the order of 350-1,350-2,350-3 from the cooling air weather side cooled body.
The configuration relation of the first fin 34a, the second fin 35a and the 3rd fin 36a so long as the space 34b between the first fin 34a greater than the space 35b between the second fin 35a, space 35b between the second fin 35a gets final product greater than the scheme of the space 36b between the 3rd fin 36a, is not particularly limited.Reason is, if the words of described scheme, can suppress the air quantity of the cooling air by the second radiating fin group 35 and the 3rd radiating fin group 36 and the reduction of wind speed, thereby and the number of the first fin 34a and the second fin 35a temperature that reduces the cooling air that can suppress to pass through the first radiating fin group 34 and the second radiating fin group 35 rise.As shown in Figure 8, the cooling device 31 of the second embodiment and the cooling device 21 of the 3rd embodiment are same, the spacing of fin that is configured to the first radiating fin group 34 and the second radiating fin group 35 is the relation of integral multiple, and the second radiating fin group 35 and the 3rd radiating fin group's 36 spacing of fin is the relation (among Fig. 8, the first radiating fin group 34, the second radiating fin group 35, the 3rd radiating fin group's 36 spacing of fin is 4:2:1) of integral multiple.And, make the first radiating fin group 34, the second radiating fin group 35 and the 3rd radiating fin group's 36 the phase place of spacing of fin consistent.That is to say, same plane at each the first fin 34a configures the second fin 35a of the second radiating fin group 35 and the 3rd radiating fin group's 36 the 3rd fin 36a, and then, the binary position of width of space 34b configures the second fin 35a between with the first fin 34a, and the position of the width quartering of space 34b configures the 3rd fin 36a between with the first fin 34a.
So, by the fin configuration same with cooling device 21, become following structure, that is, passed through cooling air among the first radiating fin group 34 in the second radiating fin group 35 who is disposed at the first radiating fin group 34 downwind sides and be disposed among the 3rd radiating fin group 36 of the second radiating fin group 35 downwind sides and flow swimmingly.
In the cooling device 31 of described the second embodiment, for the air quantity that prevents cooling air, the reduction of wind speed and the confusion that flows of cooling air, contact to form radiating fin group boundary portion 38-1 by the first radiating fin group 34 and the second radiating fin group 35, contact to form radiating fin group boundary portion 38-2 by the second radiating fin group 35 and the 3rd radiating fin group 36.Radiating fin group boundary portion 38-1,38-2 can make the radiating fin group of suitable adjacency separately form space between the radiating fin group as required as the cooling device 21 of the 3rd embodiment.
Then, use Fig. 9, the deblocking temperature that is heated of the cooling device 41 of be heated deblocking temperature and the conventional example of the cooling device 21 of the 3rd embodiment is described.Should illustrate, the deblocking temperature that is heated be with the same condition of Fig. 4 under tried to achieve by numeric value analysis.That is to say, the structure of the cooling device 21 of the 3rd embodiment that uses in numeric value analysis is identical with said structure.The structure of the cooling device 41 of conventional example is, the length of fin 44a is the width sum of space 28-1,28-2 between the length of length, the 3rd fin 26a of length, the second fin 25a of the first fin 24a and radiating fin group, radiating fin group 44 spacing of fin is identical with the 3rd radiating fin group 26, in addition, identical with cooling device 21 structures of in numeric value analysis, using.Carry out numeric value analysis with following condition, will from the heat of the total 11000W of each heater element 250-1,250-2,250-3,450-1, the impartial heating of 450-2,450-3 respectively heat be input to the piece 22,42 that is heated, and the cooling air that blows to the first radiating fin group 24, radiating fin group's 44 front all is 20 ℃, wind speed 5.8m/s.Should illustrate, in Fig. 9, in order relatively to be given in the lump the data of the cooling device 1 shown in Fig. 4.
As shown in Figure 9, about the piece windward section of the being heated temperature of cooling device 21, although also will rise than the cooling device 41 of conventional example, temperature and the conventional example of the piece central portion that is heated roughly are equal extent, and the temperature of the piece leeward of being heated section is lower than conventional example.And the cooling device 21 of the 3rd embodiment is compared with the cooling device 1 of the first embodiment, and the temperature of the piece leeward of being heated section is lower.Therefore, the cooling device 21 of the 3rd embodiment is by being increased to 3 with the mutual different radiating fin group of spacing of fin, compare the cooling capacity that cooling device 1 further improves downwind side, can further realize the homogenizing of cooling capacity, and total weight is reduced.
Then, use Figure 10 that the radiating fin group boundary portion 38-1 of the cooling device 31 of the localization method of space 28-1,28-2 between the radiating fin group of the cooling device 21 of the 3rd embodiment and the second embodiment, the localization method of 38-2 are described.Should illustrate, the line chart of Figure 10 is that among Figure 10, " fin front end " refers to the fin end facing to a side of cooling air weather side from the Temperature Distribution on the radiating fin group 44 suitable fin 44a surfaces of selecting of the cooling device 41 of conventional example.
The position of the position of space 28-1,28-2 and radiating fin group boundary portion 38-1,38-2 is not particularly limited between the radiating fin group, can suitably select, but, viewpoint from the cooling capacity that improves downwind side, preferably, similarly determine based on the fin surface Temperature Distribution with the cooling device 1 of the first embodiment.That is to say, space 28-1,28-2 between the radiating fin group or radiating fin group boundary portion 38-1,38-2 are positioned, so that cut apart fin 44a in the position of the temperature difference Δ T/3 that the temperature difference Δ T trisection on the fin 44a surface of a plate of conventional example can be cut apart, form the first radiating fin group 24,34, the second radiating fin group 25,35, the three radiating fin groups 26,36.So, when space 28-1,28-2 or radiating fin group boundary portion 38-1,38-2 are set in the position of expression temperature difference Δ T/3 between the radiating fin group, can form 3 radiating fin groups in the zone that each fin surface temperature approaches.So, by so that have the first radiating fin group 24,34 of abundant cooling capacity, the second radiating fin group 25,35 spacing of fin are greater than radiating fin group 44 spacing of fin, in addition, also make the first radiating fin group 24,34 spacing of fin greater than the first radiating fin group's 4 of cooling device 1 spacing of fin, can further suppress by the air quantity of the cooling air among the 3rd radiating fin group 26,36 and the reduction of wind speed.And, because the wind speed by the cooling air among the first radiating fin group 24,34 is large, rise so can further reduce the temperature of the first radiating fin group 24,34 cooling air, can supply with and compare the lower cooling air of cooling device 1 temperature to the second radiating fin group 25, the 35 and the 3rd radiating fin group 26,36.And then, because reduce the number of the first fin 24a, 34a, so can further suppress cooling device 21,31 weight.
At this moment, based on the reason same with the cooling device 1 of the first embodiment, position at the temperature difference Δ T/3 that the temperature difference Δ T trisection on fin 44a surface can be cut apart arranges space 28-1 between the radiating fin group, 28-2 or radiating fin group boundary portion 38-1, during 38-2, the second radiating fin group 25, the second fin 25a of 35, Length Ratio the first radiating fin group 24 of 35a, the first fin 24a of 34, the length of 34a is long, the 3rd radiating fin group 26,36 the 3rd fin 26a, Length Ratio the second radiating fin group 25 of 36a, the second fin 25a of 35, the length of 35a is long.
Then, the using method of cooling device of the present invention is described., describe as an example of following using method example, by the cooling device 1,21 of embodiment of the present invention, the electric parts (for example power conversion device) that 31 coolings are carried at Move tool (for example rail truck) herein.The framework that is used for power ratio control of and external isolation fixing at the underfloor of rail truck is held the various electric partss that power conversion device etc. is used for power ratio control in framework.These electric partss are in when work heating, if heating is left out of account, then not only can heat up and can not work, and exist element by the possibility of heat damage under worst case.Therefore, must these electric partss of cooling.
Make described electric parts (below, be called heater element) abut against cooling device 1,21,31 the piece 2,22 that is heated, 32 rear side and with the piece 2,22 that is heated, 32 hot links.Within holding the framework of heater element, be provided for supplying with to cooling device 1,21,31 fan of cooling air.Cooling device 1,21,31 is set, so that large the first radiating fin group 4,24,34 of spacing of fin is towards the cooling air weather side, cooling air from fan passes through little the second radiating fin group 5,25,35 of spacing of fin from the first radiating fin group 4,24,34, in the situation that cooling device 21,31 further passes through the 3rd radiating fin group 26,36 of spacing of fin minimum.That is to say, the flow direction of the cooling air of carrying from fan becomes parallel shape for the piece 2,22 that is heated, 32 surface.
In the situation that cooling device 1,21, the heat of emitting from heater element at first is diffused into and the hot linked piece 2,22 that is heated of heater element, be diffused into the piece 2 that is heated, 22 heat is passed in the piece 2 that is heated, 22 heat pipe 3,23 bottom, the namely heating parts that embed.So, heat pipe 3,23 heat-transfer system work, the heat that will absorb in the heating part is situated between by the heat pipe 3 that extends from the heating part, 23 cooling end, is delivered to the radiating fin group of flowing who accepts from the cooling air of fan conveying, and the group is discharged into external environment condition from radiating fin.On the other hand, in the situation of the cooling device 31 that does not comprise heat pipe, the thermal diffusion of emitting from heater element to the hot linked piece 32 that is heated of heater element, the heat that has been diffused into the piece 32 that is heated is passed to the radiating fin group of flowing who accepts from the cooling air of fan conveying, and the group is released to external environment condition from radiating fin.
So, because radiating fin group's spacing of fin diminishes to downwind side successively from the cooling air weather side, so by the ventilation quantity among the inhibition weather side radiating fin group and the reduction of wind speed, can improve the cooling capacity of downwind side.Therefore, even for example increase cooling device for the power conversion device that cools off rail truck, also can positively cool off the heating part away from weather side.Should illustrate, in described user's rule, although cooling air supplied with by fan,, in the situation that framework arranges cooling device 1,21,31 outward, also fan can be set, use and to travel wind as cooling air.
